The peripheral? eur-` faceofthe -block 15 is provided with recasses 18 andl 19 for a purposehereinafter The air current producer of the apparatus'I as illustrated,com rises a cone-shaped-member 20, bladey mem rs 21, and a rin 22, thebladememhers 21 being connecte at one end in the cone-shaped member andat their opposite ends to the ring 22. While these parte are thusconnected to ther they are also to and onnte upon Vthe nio- `toi- 23'iiiany sui blemanner so. as to be thereby. mated the current' produceris so'conthatby the revolution thereof air caused to move first inadirection to the axis of rotation predetermined -paths at an an lethereto to 'diffuse the air as mov andthus ete circulation of the air inthe y 'or other place ,to beven'tilated. features however, form `no partof my present invention and are more `particularly pliation 'Sefonelofthe features o thev Y inpludes As hereinbefnm muy and then periphery onature of this invention. At its outer end each hollow arm 24 terminatesin a cup member 25 provided with a reduced extremity 26 and an internalflange 27. Within each cup member 25 there 1s a 11ning 28 of insulatingmaterial recessed to recelve a metal cone 29 rovidcd with a screwthreaded bore as clear y indicated in Fig. 4.

A lead wire 30 passes through each, of the hollow arms 24 and iselectrically connected in a suitable mannerto the correspondingmetallicco'ne 29. At the oplposite or lower end as illustrated, each oft e cup members 25 is fitted with a plug 81 having an ornamentalexterior configuration and secured in any desired yway to the cup memberor the metal coneI secured within the same. This caseor frame structurealso includes a series of tubes 82 corres ending in number with thehollow arms 2 and each tube'82 is provided with a 'linin 38of'insulating material havin a bore t erethrough. The series of tubes 2is suitably connectedto a plurality of bandsor rings 34 preferably ofdifferent diameters so as to cause vthe tubes 32 to assume an inclinedosition in order to conform generell to t e inclination at which theblades of t e air current reducerr are set. The guard or cage mem 'ralso includes a disk top 35 preferably o f insulat` ing material theupper surface adjacent the which 1S raised as indicated ai 36 while theed thereof is flanged as indicated at 37 an the under surface recessedas indicated at 38. The surface of the raised portion is such as topreferably be at 1i ht angles to the axis of the tubes 32 while as willbe understoodthe cup members 25 are so placed or lthe arms 24 so bent,as to cause these cup members 25 to be in alinement with the tubes 32when the parts are assembled. It will now be understood that the frameor cage member comprises the'supporting arms 24 with their cups 2g, an sthe-connected tubes 32 and rings or 3.4, and the top 85. In assem lingthese parts the connected tubes and bands-are placed over the rblades ofthe air' current producer and fitted attheir lower or inner ends intothe reduced portions 26 of the corresponding cup members 25 while attheir up er ends the tube mem rs 33 fit withint erecesses Y38 of the to35 which are so made as to receive them. 'ese parts 'are connected bymeans of bolts 39 which pass through openings in the raised part 36 onthe top 35 and through the bores in the linings 8B of the tubes 32 therebeing a` bolt provided for -eaoh of these tubes and each olt havingahead at one end as indicated l at 40 withl a circumferential recess' 41therein vwhile at the oiherlend each .bolt is sfre'w threaded so as to4be turned down into the screw threaded here of the' spending metal cone29. By this ineens at`v o'f contacts 47 which .ends the contacts are .at49, tll Said L vo:

will be readily apparent the guard or cage which is an integralstructure and separatelyremovable from the casin is connected theretomechanically and e ectrically to secure these parts together and providemeans for electrical clrcuits to electric lamps or other devices whichma be emplcgd for producing a desired decorative e Of course it will beunderstood that the bolts 39 may be madcwith permanent insulatingcoverin so as to be fitted into the tubes 32 instea of constructed ashereinbefore described, in which instance as will also be understood theo ening in the flan ed ortion' of the top plate 35 is sailicienty argeto Iseceivey the bolt with its insulating covering being ofsubstantially the same diameter as lthe diameter o'f the insulation onthe bolt.

Withthe structure as herein described I may also em )loy suitable meansfor changing the con ition of the air as it is discharged rorn the fan.The air may be chan ed by heating, cooling, perfuming, disin acting,humidifying, ozonizing, or otherwise treating it in the same orequivalent manners as are described in my lco- Eending application towhich reference has ereinbefore been'made. For example, the rings orbands indicated at 84 may be in the form of tubes and provided withresistance coils which are suitably connected and disconnected in andfrom one of the electric circuitsto heat the tubes and thus raise thetemperature of the airl as it is delivered from the fan. 4Suitable meansalso may be provided in these tubes for cooling the air or ashereinbefore stated,.means may be employed for perfuming, disinfecting,

humidiying or ozonizing the airhtliut these a shadev 46 or otherornamental device whic adaptsurrounds the laml bulb. The 'electricalconnections are ma ve the bolts 39 to the lam'p socket and lamp bulb bymeans eralrfly4 insulated from the cap 42 b screws and aninterveninglayler of ms'ula in lillaterial or otherwise. he contacts 4are preferably o'il'set .at the corresponding ends thereof as indicatedat'48 and 1n @sive the eircumfentielly: recessed portions are secured toand prefi these recessed as indicated: being adapted to re? of the heads40 of cpbesitelv diseased een 1th a positive conductor and the othersirrespecl tiveofytheir number as negative conductors in order to producedifferent lighting effects. It will furthermore be apparent that asillustrated in the smaller types of ventilator fans the guard or cagemember may be made conical but in larger types thereof it may beadvisable to make it hexagonal or octagonal, or even spherical, or insome other coniguration which however, has no bearing on the subjectmatter of this invention.

In the base 10 I prefer to employ a series of terminals indicated at 52,53, 54, together with contacts indicated at 55 and 56, and a switch arm57 which at one end is pivotally connected to the terminal 52 andintermediate of its ends is adapted to bear against either the contact55 or the contact 56. The positive lead wire from the source ofelectricity to the ventilator fan is indicated at 58 and is carried`andconnected to the terminal 52. A lead Wire 59 extends from the terminal52 to the terminal 53 and to one of the terminals of the light socket,and as will be understood, this lead Wire as diagrammatically indicatedin Fig. 7 includes the lead Wire 30, a conductor bolt 39, a contact 47,and either of the lead wires 50 or 51 as hereinb'efore described. 4Alead Wire 60 extends from the other terminal of the lamp socket to thecontact 54 which is connected by alead Wire 6l to the negative line, andthe lead 60 of course includes either one of the lead Wires 50 or 51 andthe other side of the circuit includes one or all of the other conductorbolts forming part of the guard or cage. A lead Wire 62 extends from thecontact 54 to one of the motor terminals while the other' motor terminalis connected by a lead 63 to the contact 55. From the diagrammatic planas shown in Fig. 7 it will be apparent that the light may be usedy avertical position and at its lower end made to turn in a thrust bearing,if it were not properly ventilated it would overheat in a comparativelyshort time unless a motor of considerably larger capacity were employedthan is necessary to operate the fan or air current producer, which eventhen if not ventilated would produce an excessive,

amount of heat. In the structure as herein indicated it is to be notedthat a series of openings 64 are provided in the casing beneath themotor for the admission of air so that through the operation of the fanor 'air current producer there is a positive draft or current of aircirculated around the motor at, all times so as to adequately ventilatethe interior of the casing and maintain the motor at an eliicientWorking temperature by coolin the interior a's well as the exterior of te motor, which of course permits the use of a motor of smaller capacitythan would otherwise have to be employed, the y air currents passingthrough the openings 64 and through the Ventilating recesses 18 in theblock 15 as hereinbefore described, as well as through the spaceprovided for thispurpose between the exterior of the motor and theinterior of the casing. I

As herein described the casing or frame is an ornamental structure inwhich the motor is mounted and the device supported, but as will beunderstood in some instances this casing may be dispensed'vith and theguard or cage connected to the frame of the motor either directly orthrough arms or other suitable supports'projecting therefrom in the samemanner as the arms herein described extend or project from the casing.
